ide: set/clear drive->waiting_for_dma flag in the core code
Set/clear drive->waiting_for_dma flag in the core code instead of in ->dma_setup and ->dma_end methods. There should be no functional changes caused by this patch. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
